Abstract
The role of the final-state
NN-rescattering (
NN-FSI) in the polarization observables of the inclusive reaction
d
(
γ

π
−
)
p
p
, involving polarization of the photon beam and/or the deuteron target, is investigated. Various single- and double-spin asymmetries are studied with respect to the influence of such interaction effect and numerical predictions are given for forthcoming experiments. It has been found that the effect of
NN-FSI is quite important for the single-spin asymmetries
Σ,
T

T

and
T

and the double-spin asymmetry

, whereas it is much less important for the vector target asymmetry

and other beam-target double-polarization asymmetries. Furthermore, we found that the inclusion of the
NN-FSI improves the description of the LEGS data for the linear photon asymmetry.
